Ultrasound is the safest investigation during pregnancy and with advancing science it has become a routine test to evaluate the fetus/baby.
Many Patients are worried and confused about what will be the best time for ultrasound. Timing of ultrasound is very important to obtain proper information and follow up the pregnancy.
Note: Pregnant patient must have her valid ID proof & a valid prescription with sign and stamp of the referring doctor.
Ideally the timings to follow should be:
- Documenting and Dating the Pregnancy – around 8-9 weeks (from LMP)
- NT scan – around 12 weeks (from EDD / LMP)
* Early Anomaly Scan – around 15-16 weeks (if needed based on previous ultrasound)
- Anomaly Scan / Level II + Fetal Echocardiography / Fetal Echo – around 19-22 weeks
* Follow up scan for specific structure – around 24-26 weeks (if needed based on previous ultrasound)
* Fetal Echocardiography alone – around 22-25 weeks
- Growth scan (always with Doppler) – around 28-30 weeks
- Follow up Growth scan (always with Doppler) – around 35 weeks
- Growth scan monitoring (always with Doppler) – as required based on any problem in previous scans
A scan may also be required in between based on any specific complain of the mother or if the doctor feels there is some complication or the doctor needs some specific information regarding the progress of pregnancy.
